1. Product Introduction, Brand & Series
Brand: GE Fanuc (General Electric)
Series: IS200 / Mark VI / EX2100 Excitation / Turbine Control Systems
The IS200ERIOH1A is an I/O Regulator Board used in EX2100 Excitation Regulator and Mark VI control systems. It acts as the interface between customer I/O and system I/O, supporting both simple and redundant setups. The board handles input/output regulation, signal conversion and aggregation, and routes data between terminal boards (e.g. ECTBG2, EPCT) and regulator backplanes (ERBP / ERRB). It’s designed for reliability, high performance under heavy industrial conditions, and serves a central role in excitation control.

3. Applications
Some typical applications where IS200ERIOH1A is used:
-
In power plants, within turbine generator excitation systems, to manage both system‑I/O and customer external I/O.
-
In redundant excitation regulator architectures, to bridge control units, terminal boards, and external I/O to maintain system stability.
-
In industrial automation environments where both analog/digital external signals and system internal I/O must be managed under harsh conditions.
-
For system upgrades or maintenance, replacing or adding modules in existing Mark VI / EX2100 cabinets.
-
In situations requiring accurate and reliable I/O for excitation regulator logic, where signal integrity and redundancy are required.
